2. Installation

1. Choose the desired location for your speaker. Ensure that there are no electrical wires, pipes, or other obstructions in the area where you will be cutting the hole for the speaker.
2. Place the Perfect Fit template on the ceiling and trace the outline of the speaker hole with a pencil.
3. Using a drywall saw or a suitable cutting tool, carefully cut out the hole along the traced line.
4. Feed the speaker wire through the hole and strip the ends to expose the bare wire.
5. Insert the speaker into the hole, ensuring that the rotating cams are in the open position.
6. Tighten the rotating cams by turning them clockwise. This will secure the speaker to the ceiling and create a vibration-free installation.

3. Speaker Connections

1. Connect the stripped ends of the speaker wire to the speaker terminals on the back of the speaker. Ensure that the positive (+) wire is connected to the red terminal and the negative (-) wire is connected to the black terminal.
2. Connect the other end of the speaker wire to the corresponding speaker output terminals on your audio receiver or amplifier.

4. Painting the Grille

1. Remove the grille from the speaker by carefully prying it off with a flathead screwdriver or similar tool.
2. Paint the grille using a non-metallic paint, ensuring that the paint does not clog the holes in the grille.
3. Allow the paint to dry completely before reattaching the grille to the speaker.

5. Troubleshooting Tips

• If there is no sound, check the speaker connections and ensure that the speaker wires are connected to the correct terminals on both the speaker and the receiver/amplifier.
• If the sound is distorted, reduce the volume on your receiver/amplifier and check the speaker connections.
• If the grille keeps falling off when installed on the ceiling, ensure that it is properly seated and pushed all the way in.
